help on tickets after swiss travel pass purchased

Someone else can maybe help more, but you don't really need tickets with the STP, except for the panorama trains. You just get on the train. Make sure to have the STP and your passport handy to show train attendant. Typically what I did since I was new with Switzerland, I went to the ticket counter and they'd print a "psuedo" ticket so I'd know times and transfers, etc. They always spoke English and were quite helpful. Maybe, make a paper copy of the pass?

Unless something has changed , the STP and online accounts don't link. With the STP, you just walk onto the eligible trains, boats, cogwheels, etc. Your STP can be added to your Apple Wallet, which is nice.
Download the SBB app for schedules, connections, platform #'s, ect.
Enjoy this beautiful country!

The pass IS your ticket, you don't get a ticket for the route if it's included. When someone comes through the train checking tickets, you show your pass + your ID, not a ticket. That's part of the beauty of the pass. You just hop on/off any included route without thinking about tickets whatsoever.

I can't confirm what the first class upgrade is without knowing your exact date of travel.

Using swisspass is really meant more for long term travelers/residents because of certain passes we use that integrate with a long term charge account. You don't need to worry about any of this. Just keep the QR code of your pass on your phone in your files or photos section, it doesn't need to be hooked to anything SBB related for it to work and make sure to travel with your ID.

In your personal information in the app choose that you have a “GA Travelcard, 2nd class". This is the yearly travel pass that Swiss use. It is not something you will show the train staff, just that it will help you see what routes are covered by the STP.

Then when you look at a Luzern - Bern train you will see “tickets from CHF 20.00” (or whatever amount). Click on that, the next screen now tells you that your cost is CHF 0.00 and “journey covered by your GA Travelcard”.

 My app might look different from yours because I do have a swisspass. If the above does not work, try setting up a co-passenger and for them choose GA Travelcard, 2nd class, then look up routes using that.

This can be a helpful way to see what is covered and what is not.

In addition to that, you can look at this map. There is a dropdown menu - choose "Swiss Travel Pass". Click on the ‘I’ to see what the colours and dots vs solid lines mean as far as discounts. Zoom in to the areas that you want to travel to see more detail. All solid lines are within your ‘free’ travel zone.

For a first class upgrade:

Choose the time and route you want, click on it to get to the second screen. Under “additional offers” you will see “Point-to-point class upgrade”. The one I randomly choose for Tirano to Chur says CHF 23.50. 

Sometimes there is a supersaver saver discount available, You will see it with a % sign next to it. This can be used only on that specific train, which in your case if fine because your seat reservation is valid on a specific train.

Edited to add: I am not sure if the STP allows you to upgrade at the reduced GA price or if you have to pay the regular upgrade price. You can check with train staff when you are here. You do not need to purchase the upgrade until just before getting on the train for that specific journey.

The STP does allow you to buy the reduced class upgrade. So you are fine pretending you have the GA. The only place where pretending you have the GA will not work are a few mountain railways (like the Jungfrau Railway) where the STP only gives 25% off. But these are only a handful of exceptions.

Our Bernina Express is scheduled Sept 10 2025. Tirano to Chur departing 14:24

Everyone's comments very helpful!
